Key idea: Tests for a parallelogram
A quadrilateral is a parallelogram if ANY ONE of the following is true:
- Both pairs of opposite sides are parallel (definition).
- Both pairs of opposite sides are equal.
- Both pairs of opposite angles are equal.
- Diagonals bisect each other.
- One pair of opposite sides is **both equal AND parallel**.
That last one is the most efficient — only ONE pair to check, but you need both 'equal' AND 'parallel'.
Don't confuse: just 'one pair parallel' is a trapezium, not a parallelogram.
